MAX9257 Register Table
Choosing I2C Pullup Resistors
I2C requires pullup resistors to provide a logic-high level
to data and clock lines. There are tradeoffs between
power dissipation and speed, and a compromise must
be made in choosing pullup resistor values. Every device
connected to the bus introduces some capacitance even
when device is not in operation. I2C specifies 300ns rise
times to go from low to high (30% to 70%) for fast mode,
which is defined for a date rate up to 400kbps (see I2C
specifications for details). To meet the rise time require-
ment, choose the pullup resistors so the rise time
tR = 0.85RPULLUP x CBUS < 300ns. If the transition time
becomes too slow, the setup and hold times may not be
met and waveforms will not be recognized.
